Combine "Z-shaped plate" drill
In the actual drilling process, except for the drilling molds of some disc parts, most of the drilling molds are composed of a base, a "Z-shaped plate", a drill sleeve, and a limit clamping member, and the general-purpose drilling mold is "Z-shaped". The board is not adjustable, so it is not suitable for a wide range of applications. Although the "Z-shaped plate" is adjustable for the drill die assembled by the common combination jig, it is troublesome to assemble and has low precision, so it is not easy to use. To this end, we designed a set of "Z-shaped plate" drills by analyzing the various drilled parts, combined with the respective advantages of the special drill and the combined drill, as shown in Figure 1.
